Bart - V6 patch set accommodate linux coding standard (mainly in mpi3mr
headers) as you initially pointed out.
Christopher,
Can you take a look at the V6 changes as per your feedback I have updated
the series. If you are OK with the changes, I can request Martin to commit
(assuming he has no further concerns) the set. This is the only pending
item for this series.
Kashyap

This patch covers basic pci device driver requirements -
device probe, memory allocation, mapping system registers,
allocate irq lines etc.
Source is managed in mainly three different files.
mpi3mr_fw.c - Keep common code which interact with underlying fw/hw.
mpi3mr_os.c - Keep common code which interact with scsi midlayer.
mpi3mr_app.c - Keep common code which interact with application/ioctl.
This is currently work in progress.

[-- Attachment #1: Type: text/plain, Size: 24765 bytes --]
Create operational request and reply queue pair.
The MPI3 transport interface consists of an Administrative Request Queue,
an Administrative Reply Queue, and Operational Messaging Queues.
The Operational Messaging Queues are the primary communication mechanism
between the host and the I/O Controller (IOC).
Request messages, allocated in host memory, identify I/O operations to be
performed by the IOC. These operations are queued on an Operational
Request Queue by the host driver.
Reply descriptors track I/O operations as they complete.
The IOC queues these completions in an Operational Reply Queue.
To fulfil large contiguous memory requirement, driver creates multiple
segments and provide the list of segments. Each segment size should be 4K
which is h/w requirement. An element array is contiguous or segmented.
A contiguous element array is located in contiguous physical memory.
A contiguous element array must be aligned on an element size boundary.
An element's physical address within the array may be directly calculated
from the base address, the Producer/Consumer index, and the element size.
Expected phased identifier bit is used to find out valid entry on reply
queue. Driver set <ephase> bit and IOC invert the value of this bit on
each pass.

Send Port Enable Request to FW for Device Discovery.
As part of port enable completion driver calls scan_start and
scan_finished hooks.
scsi layer reference like sdev, starget etc is added but actual
device discovery will be supported once driver add complete event
process handling (It is added in subsequent patches)
This patch provides interface which is used to interact with FW
via operational queue pairs.

Watchdog thread is driver's internal thread which does few things like
detecting FW fault and reset the controller, Timestamp sync etc.

Firmware can report various MPI Events.
Support for certain Events (as listed below) are enabled in the driver
and their processing in driver is covered in this patch.
MPI3_EVENT_DEVICE_ADDED
MPI3_EVENT_DEVICE_INFO_CHANGED
MPI3_EVENT_DEVICE_STATUS_CHANGE
MPI3_EVENT_ENCL_DEVICE_STATUS_CHANGE
MPI3_EVENT_SAS_TOPOLOGY_CHANGE_LIST
MPI3_EVENT_SAS_DISCOVERY
MPI3_EVENT_SAS_DEVICE_DISCOVERY_ERROR
Key support in this patch is device add/removal.
Fix some compilation warning reported by kernel test robot.

Added h/w defined process of doing controller reset.
The driver on detection of firmware fault or any kind of unresponsiveness
in the controller (Any admin command time outs) results in resetting the
controller. The primary reset mechanisms used are either soft reset or
diag fault reset. Reset is performed if the host sets the ResetAction field
in the HostDiagnostic register to a 001b (Soft Reset) or
007b(diag fault reset). The driver after successfully resetting the
controller reinitialize the controller by going through start of the day
controller initialization procedures.The pending I/Os during the reset are
returned back to SML for retry.

This operation requests that the IOC update the TimeStamp.
When the I/O Unit is powered on, it sets the TimeStamp field value to
0x0000_0000_0000_0000 and increments the current value every millisecond.
A host driver sets the TimeStamp field to the current time by using an
IOCInit request. The TimeStamp field is periodically updated by host
driver.

This patch allows SSU and Sync Cache commands to be sent to the controller
instead of driver returning DID_NO_CONNECT during driver unload to flush
any cached data from the drive.

The controller hardware can not handle certain unmap commands for NVMe
drives, this patch adds support in the driver to check those commands and
handle as appropriate.

Register driver for threaded interrupt.
By default, driver will attempt io completion from interrupt context
(primary handler). Since driver tracks per reply queue outstanding ios,
it will schedule threaded ISR if there are any outstanding IOs expected
on that particular reply queue. Threaded ISR (secondary handler) will loop
for IO completion as long as there are outstanding IOs
(speculative method using same per reply queue outstanding counter)
or it has completed some X amount of commands (something like budget).

This test of "shost" is unnecessary. If you set the drvdata before
the .probe() method returns success, you will always get valid drvdata
here. And you do:
mpi3mr_probe
mpi3mr_init_ioc
mpi3mr_setup_resources
pci_set_drvdata(pdev, mrioc->shost)
Sure, it's *possible* that a random memory corruption will clear out
the drvdata pointer, but there's no point in testing for that.

This looks possibly wrong. mpi3mr_cleanup_ioc() takes a "reason",
which looks like it should be MPI3MR_COMPLETE_CLEANUP (0),
MPI3MR_REINIT_FAILURE (1), or MPI3MR_SUSPEND (2).
This should at least use the enum, and it looks like it should use
MPI3MR_SUSPEND instead of passing the MPI3MR_REINIT_FAILURE value.

Why is mpi3mr_cleanup_resources() needed here? It frees IRQs,
iounmaps registers, calls pci_release_selected_regions(), etc.
Very few other drivers do this, and I don't think it's necessary for
suspend. And if you don't clean it up here, you won't need to
re-initialize it during resume.
I'm asking because I want to convert this from the legacy PCI power
management model to the generic PM model. The generic model works
like this:
suspend_devices_and_enter
dpm_suspend_start(PMSG_SUSPEND)
pci_pm_suspend # PCI bus .suspend() method
mpi3mr_suspend <-- device-specific stuff
suspend_enter
dpm_suspend_noirq(PMSG_SUSPEND)
pci_pm_suspend_noirq # PCI bus .suspend_noirq() method
pci_save_state <-- generic PCI
pci_prepare_to_sleep <-- generic PCI
pci_set_power_state
...
dpm_resume_end(PMSG_RESUME)
pci_pm_resume # PCI bus .resume() method
pci_restore_standard_config
pci_set_power_state(PCI_D0) <-- generic PCI
pci_restore_state <-- generic PCI
mpi3mr_resume # dev->driver->pm->resume
Notice that in the generic model the PCI core takes care of
pci_save_state(), pci_set_power_state(), etc., and the device-specific
stuff is done before the generic PCI suspend, and after the generic
PCI resume.
mpi3mr_cleanup_resources() is problematic because the device-specific
stuff should be done *before* the generic PCI part, but you call it
*after* the generic PCI part. I think it would be *possible* to do it
after by making a mpi3mr_suspend_noirq() method, but there are hardly
any drivers that do that, and I think mpi3mr_cleanup_resources() is
unnecessary here anyway.

Sorry for the noise about this part, I see you fixed this later with

Read PCI_EXT_CAP_ID_DSN to know security status.
Driver will throw an warning message when a non-secure type controller
is detected. Purpose of this interface is to avoid interacting with
any firmware which is not secured/signed by Broadcom.
Any tampering on Firmware component will be detected by hardware
and it will be communicated to the driver to avoid any further
interaction with that component.
